Definitions

  • the invention relates to an apparatus for polishing flat ceramic products, for example tiles or slabs made of porcelain stoneware.
  • the invention further relates to an apparatus for conveying objects having a flat supporting base, in particular ceramic tiles along a conveying line during a step of the production cycle.
  • Machine tools which are fed with tiles that have already been fired in kiln, so that such tiles can be treated on the surface thereof by means of abrasive or cutting tools, through which the tiles are subjected to polishing on the face that will be visible after tile laying.
  • the above mentioned polishing machine tools are provided with cooling means for cooling the interface region between tool and tile, said cooling means consisting of jets of lubricant-coolant liquid, in particular water, which completely floods the surface of tiles to be worked.
  • the liquid jets can be manually positioned quite roughly and exaggerated water flows are therefore required, to be sure that the working surface is properly sprayed.
  • polishing devices For at least partially overcoming the above described drawbacks, polishing devices have been developed, said polishing devices being suitable for treating "green" tiles, i.e. pressed and dried, but not yet fired tiles.
  • the Italian Patent for industrial invention no. 1.269.384 discloses a polishing machine, particularly for ceramic tiles made of porcelain stoneware, comprising a first polishing unit and a second polishing unit, consecutively arranged, through which said tiles are advanced along a pre-established direction by means of a conveyor belt of a conveying line.
  • the first polishing unit is provided with a polishing tool having cylindrical shape and advantageously made of abrasive material, said polishing tool being positioned above the conveyor belt so as to interact with the surface of the tiles carried by the conveying line.
  • the tool is rotationally supported by a supporting frame so as to be able to rotate around a respective longitudinal axis arranged perpendicularly to the advancing direction of the tiles.
  • the second unit is provided with a further polishing tool having the shape of a disc, also advantageously made of abrasive material.
  • the further tool is positioned above the conveying line and is rotated by a motorized shaft arranged substantially in a vertical position: thus, the further tool can interact with the upper surface of the tiles removing from said tiles part of the material forming the tiles for obtaining on each tile a polished surface.
  • the second unit further comprises, at the active surface of the disc shaped tool, a conduit suitable for blowing pressurized air, arranged for removing from said active surface the powders generated during the polishing operations.
  • the disc shaped tool is obtained by mutually placing side by side a plurality of abrasive sectors so that the escapes between a sector and the adjacent ones form a preferred path for the outflow of the pressurized air.
  • a drawback of such machine is that, if the cylindrical tool of the first unit is rotated around a rotation axis that does not exactly coincide with its geometrical axis, polished tiles are obtained having a non perfectly flat upper face.
  • the resulting tiles may be provided with a face that is to be visible after laying, the surface of which has a series of undulations consisting of a plurality of protrusions alternated with a respective plurality of depressions.
  • the cylindrical tool can comprise, at one or more points of the active surface thereof, grains of abrasive material having particular hardness that produce, on the tiles with which said grains come into contact, grooves extending longitudinally through the whole extension of the tiles. Said groove can compromise the aesthetical properties of the tiles, sometimes even making said tiles unusable for being laid.
  • particles of material removed from a transiting ceramic product can remain "trapped" between the tile surface and the portion of the tool interacting with said tile, causing scratch defects similar to those described above. Such defects are particularly evident if the removed particles have significant size and/or particular hardness.
  • a further drawback of the machine disclosed in IT 1.269.384 consists in that the disc shaped tool of the second polishing unit tends to adhere to the ceramic supports with which it interacts, since the pressurized air flowing through the escapes arranged between an abrasive sector and the adjacent ones is subjected to a centrifugal motion and tends, therefore, to create a depression between the tool and the underlying tiles. Said depression keeps the tiles attached to the tool.
  • a "suction cup" effect is created between the tile face and the tool active surface, which makes difficult transferring the tiles on the conveying line, particularly when said tiles leave the second polishing unit. This can cause damage, or breakage of the tiles, which are quite brittle since they have not yet been fired.
  • Prior art comprises apparatuses for conveying ceramic tiles comprising a conveyor belt whereon the tiles that are to be moved along an advancing direction lie.
  • the conveyor belt is wound on a pair of end rollers, one of which is motorized by suitable actuating means.
  • the apparatuses for conveying ceramic tiles further comprise adjustable guiding tapes performing a lateral guiding function for the tiles and enabling tiles of different size to be moved.
  • Said guiding tapes lie on the two peripheral regions above the plane defined by the conveyor belt so as to leave uncovered a central portion of such belt. Such portion can be used for moving the tiles.
  • Said guiding tapes rest on the conveyor belt along the whole plane involved in moving the tiles and are wound on a portion of the end rollers, always remaining in contact with such conveyor belt.
  • the apparatus further comprises a roller driven independently from said conveyor belt, such roller enabling said tapes to move at a peripheral speed exactly equal to the conveyor belt speed.
  • a drawback of such apparatus consists in that it requires a pair of driving devices, the first of which is arranged for actuating the conveyor belt, the second for moving the guiding tapes. That causes a significant increase of the apparatus costs, and multiplies the breakage risks and the maintenance charges.
  • a further drawback consists in that, if the apparatus has to be adjusted for changing the size of the tiles to be conveyed, the guiding tapes have to be removed and then repositioned, or replaced with other guiding tapes of suitable width, which implies a decrease in the machine efficiency and a loss of productivity.
  • a planing machine provided with one drive head for planing tiles translated by a planing line comprising a slat conveyor belt formed by a plurality of slats constrained one consecutively to another by flexible joints.
  • a wheel on which the slat conveyor belt is partially wound, can be displaced with a vertical direction component.
  • a cam solidly associated to the wheel, rests on a fixed roller, and is shaped so that a flexible joint joining a first slat interacting with the wheel and an adjacent slat not interacting with the wheel is not subject to vertical displacements.
  • a first purpose of the present invention is to improve the apparatuses for polishing unfired flat ceramic products.
  • a second purpose of the invention is to provide an apparatus for polishing unfired flat ceramic products that is provided with high productivity.
  • a third purpose of the invention is to provide an apparatus which allows unfired polished, flat ceramic products having a very high surface finishing level to be obtained.
  • a fourth purpose of the invention is to provide an apparatus for polishing unfired flat ceramic products, said apparatus allowing finished products having a visible face substantially free from scratching defects to be obtained.
  • a fifth purpose of the invention is to obtain a polishing apparatus for unfired ceramic products wherein transferring such products through the working units is not compromised by the action of the abrasive means.
  • a sixth purpose of the present invention is to improve the apparatuses for conveying objects with flat supporting base, in particular ceramic tiles.
  • a seventh purpose of the invention is to provide an apparatus for conveying objects with flat supporting base wherein said objects are precisely guided along their path.
  • An eighth purpose of the invention is to provide an apparatus for conveying objects with flat supporting base wherein the mechanical components are subjected to less heavy working conditions.
  • a ninth purpose of the invention is to make less onerous and quicker adjusting the line in case of size change of the objects to be conveyed.
  • an apparatus for polishing products as defined by the features of claim 1.
  • the apparatus is provided with adjusting means arranged for controlling the pressure exerted on the ceramic products by the operating head means and by the further operating head means.
  • the adjusting means consists of a detecting device for detecting the electric current absorbed by a motor coupled with a spindle shaft supporting the abrasive disc means, or the further abrasive disc means, such device being suitable for sending an electric signal to an actuator coupled with the spindle shaft in order to change the axial position thereof and, respectively, to change the pressure of the abrasive disc means, or of the further abrasive disc means, on the ceramic supports.
  • an apparatus for polishing products, in particular unfired ceramic tiles, comprising operating head means provided with abrasive disc means suitable for machining an outer surface of said products, characterized in that, said abrasive disc means has a continuous band of abrasive material.
  • moving means is provided suitable for advancing said products along an advancing direction so as to bring said products into an operating configuration below said abrasive disc means.
  • tool means arranged for polishing products, in particular unfired tiles, comprising abrasive disc means suitable for interacting with an outer surface of said products, characterized in that, said abrasive disc means has a continuous band of abrasive material.
  • said guiding means comprises fixing means which can be associated with coupling means with which said conveying means is provided.
  • said coupling means is obtained in said conveying means so as to define a plurality of rows arranged parallel to said advancing direction.
  • Such rows are spaced by pre-established distances, said distances being chosen so as to allow objects belonging to a wide range of sizes to be moved.
  • said guiding means comprises a plurality of curb means successively arranged at a pre-established distance one from another.
  • the guiding means are quite flexible and therefore the risks of damaging and breaking said guiding means when it is arranged along non rectilinear trajectory, for example when it is wound around rollers, are remarkably reduced.
  • conveyor belt means comprising coupling means arranged for removably coupling with guiding means suitable for guiding said objects along an advancing direction.
  • guiding means which can be operatively associated with conveyor belt means for guiding objects having a flat base resting on said conveyor belt means, comprising fixing means suitable for removably fixing said guiding means to said conveyor belt means.
  • a polishing apparatus 1 comprising a conveying line 2 arranged for advancing ceramic tiles 3 along an advancing direction indicated by the arrow F.
  • the conveying line 2 comprises a conveyor belt 4 wound on a pair of end rollers 5, one of which is motorized, the conveyor belt 4 extending between a removal line 6 for removing the tiles 3 from a pressing station, or from a drying station, and a transferring line 7 for transferring said tiles towards the firing kiln.
  • the polishing apparatus 1 comprises a first polishing unit 8, supported by a frame 9 by means of a bridge support 10 extending above the conveying line 2, and a second polishing unit 11, positioned upstream of said first unit 8 with respect to the advancing direction of the tiles 3 and similarly supported by the frame 9 by means of a respective further bridge support 12.
  • the first polishing unit 8 is provided with a polishing head 13 comprising a disc shaped polishing tool 14, advantageously consisting of abrasive material, possibly comprising diamond inserts.
  • the polishing tool 14 is fixed to a spindle 15 by means of a support 16, having a section corresponding to the section of the polishing tool 14.
  • the support 16 is coupled to the free end of a shaft 17 of the spindle 15: the other end of said shaft 17 being coupled with an electric motor 18.
  • the end of the shaft 17 coupled to the support 16 is provided with a cavity 19 intended to receive pressurized air through an annular fitting 20, or rotating joint, peripherally rotationally coupled with such shaft: it is noted that inserting pressurized air through the annular fitting 20, as shown by the arrow F1, allows the polishing powders to be removed from the working region.
  • the belt 4 is slidingly supported by a sliding plane 21 which is part of the frame 9 of the polishing apparatus 1, a layer 22 of anti-wear material being possibly arranged therebetween, said layer 22 being removably coupled with said sliding plane 21.
  • the polishing tool 14 comprises grinding wheel means 23 so shaped as to have a continuous annular band 24 of abrasive material.
  • the surface of the grinding wheel means 23 is free from radially arranged grooves or escapes and since pressurized air flows out of the cavity 19, phenomena of adhesion of the polishing tool 14 to the tiles 3 are prevented.
  • the tiles 3 can more easily exit from the first unit 8 when the polishing operations are over without being subject to damages or breakage.
  • the shaft 17 is rotatably supported by a sleeve 25, which can slide vertically in a guiding case 26 connected to the bridge support 10.
  • a plate 27 is fixed, a height adjusting device 28 for adjusting the height of the polishing tool 14 being supported by said plate 27.
  • the device 28 comprises a plate 27 fixed to the upper end of the sleeve 25, said plate 27 being laterally provided with an extension 30 provided with a seat for rotatably coupling with a positioning screw 31, extending parallel to the sleeve 25: said screw 31 being actuated by a gear motor unit 32, supported by the plate 27.
  • the positioning screw 31 is engaged with a nut screw 33 inserted into a seat housed into a block 29 connected to the case 26.
  • the control of the gear motor unit 32 is obtained by means of an electric signal proportional to the absorption of the motor 18, so that, when such absorption exceeds a pre-established threshold value, the gear motor unit 32 acts on the screw 31 to raise the polishing tool 14: thus it is also possible to polish brittle supports, without causing their undesired damages or breakages.
  • the polishing unit 8 is provided with suction hoods 34 coupled with vacuum means 34, not shown, for removing the polishing powders, as shown by the arrow F2.
  • the second polishing unit 11 is provided with a further polishing head 35 comprising a further disc shaped polishing tool 36, substantially equal to the disc shaped polishing tool 14 of the polishing head 13.
  • the further polishing head 35 is exactly similar to the polishing head 13; a corresponding similarity can be found also between the respective operations.
  • the further polishing head 35 is provided with a further height adjusting device 28a for adjusting the height of the disc shaped polishing device 36, said further height adjusting device 28a being carried out in the same manner as the adjusting device 28 described with reference to Figure 3 .
  • the further polishing tool 36 is made so as to have a continuous annular band of abrasive material.
  • a conveying apparatus 101 comprising conveying means 102 arranged for conveying ceramic tiles 3 along an advancing direction indicated by the arrow F.
  • the conveying means 102 comprises a conveyor belt 104 wound on a pair of end rollers 105, one of which is motorized.
  • Each of such end rollers has an outer cambered surface 105a, i.e. such that the diameter of the roller measured on the centreline is slightly greater than the diameter measured of the end sections. This allows the belt 104 to be kept centred on said rollers 105, preventing the translation of said belt 104 in a transverse direction with respect to the advancing direction F.
  • the conveying apparatus 101 further comprises guiding means 106, capable of being removably associated with the belt 104 and arranged for guiding the tiles 3 during the conveying operations.
  • the guiding means 106 comprises a plurality of mutually aligned curbs 107. Each curb is spaced from the adjacent curbs 107 by a pre-established distance. Thus, when the belt 104 winds on the end rollers 105, the curbs 107 fixed to said belt 104 are free to elastically deform, adapting to the curvature of the end rollers 105, without being subjected to damages or breakages.
  • the guiding means 106 comprises fixing means 108 that can be associated with coupling means 109, with which said conveying means 102 is provided.
  • the coupling means 109 comprises a plurality of inserts 110, each of which provided with a threaded hole 111, having a shaped profile 110a and inserted into respective dovetail seats 112 obtained in the conveyor belt 104 during the production thereof.
  • the inserts 110 are therefore embedded into the material, for example elastomeric material, forming the belt 104, so that the threaded hole 111 opens to the outer face 104a of the belt 104, i.e. onto the face on which the tiles 3 to be conveyed are resting.
  • Such inserts 110 are positioned in the conveyor belt 104 so as to define a plurality of rows 113, 114, 115, 116, 117, 118 arranged parallel to the advancing direction F.
  • the fixing means 108 comprises a plurality of screws 119 suitable for engaging into the threaded holes 111 to fix the curbs 107 to the conveyor belt 104. If the conveying apparatus 101 has to be adjusted to change from conveying tiles 3 having a certain transverse size, as shown in configuration A of Figure 5 , to conveying tiles 3 having a different transverse size, as shown in configuration B of said Figure 5 , it is sufficient to remove the screws 119 uncoupling them from the threaded holes 111 in which they were engaged, to remove the curbs 107 from first dual rows 113 and 118 and to reposition said curbs 107 at the inserts 110 respectively belonging to second dual rows 114 and 117.
  • the rows 113, 114, 115, 116, 117, 118 are separated by pre-established distances, chosen so as to allow tiles belonging to a wide range of sizes to be conveyed, said sizes being indicatively specified as Y and Z. In particular, such distances correspond to the most common tile sizes on the market.
  • the coupling means 109 may comprise a plurality of further inserts 120, each provided with a further threaded hole 121, said inserts 120 being inserted into respective further seats 122 obtained in the conveyor belt 104.
  • the further inserts 120 are therefore embedded into the material forming the conveyor belt 104 so that the further threaded hole 121 opens to the inner face 104b of the belt 104.
  • through holes are made in the belt 104, such holes being arranged for allowing the screws 119 of the fixing means 108 to engage into said further threaded holes 121. Since the seats 122 are obtained in the lower portion of the conveyor belt 104, there is no risk that the further inserts 120 are removed from the further seats 122 when said conveyor belt 104 winds on the end rollers 105.
  • the coupling means 109 and the fixing means 108 may comprise pressure-snapping inserts.
  • the coupling means 109 and the fixing means 108 may comprise bayonet connecting elements.
